You are asking two questions ...

How to add a middle level value:

Add extra codes to the Arduino to send for different levels, like

a,b,s,d for 4 levels, or h = half full.

Add extra IF/then/ELSEIF parts to your IF/THEN check of the code for the other code values,

using the blue mutator box on the IF block.

How to stop the sound using Button1:

There are two ways to do it:

  1.  Have the start/stop button switch the Clock1.Enabled value on/off, using the NOT block. 

Rename the button to btnStartStop,

Change its text to Start

When clicked , if button text = Start, switch to 'Stop' else switch to 'Start'

set Clock1.Enabled to not(Clock1.Enabled)

  2.  Have the button only silence the alarm sound but keep checking:

Rename the button to btnAlarmOnOff,

Change its text to 'Alarm On'

When clicked , if button text = 'Alarm On', switch to 'Alarm Off' else switch to 'Alarm On'

In Clock1.Timer, before turning on sound, check if btnAlarmOnOff.Text = 'Alarm On' before letting it play the sound.

From what I see in your Arduino code,

you are sending a 

  '1' for full, 

 '2' for empty, and

 '3' for half full.

Since all your transmissions are single letters, you only

need to request 1 byte at a time (if there are bytes available.)

If you can't figure out the blocks part,

post your exported .aia file here so some one

still awake can add them for you.

P.S.  I am not a Doctor.

this is my project I saved as aia and uploaded.

If you're not Dr I wish you will be : ))

See attached for how I did it.

I dumped your extra label and used only one label, for simplicity.

The extra labels did not seem necessary to me, since all you were doing

was changing text and background color.

If you want to fancy this up, send the delay value and display it on a canvas bar graph.

Your 1 ms clock speed was way too fast, so I slowed it down to 100ms.

I also switched the button to a Mute/Play option,

where it displays what will happen if you push it,

and renamed it for my sanity.

It's up to you to test this.

Oh, and I switched from the Sound component to a Player component,

to get the Player block that tells me if the Player is still playing the prior request.

This avoids overlap of the sound.

you are king, it is work good thank you very much, just one more thing I need when be Full automatic show me number of trash like T1 

and I need one more line ( very good ).

Thank you, you make me happy

[Abraham Getzler]

when be Full automatic show me number of trash like T1 

???

What kind of number is T1?

ABg

 

[M]

like name or number of trash and I need one more line ( very good )  :))

I don't understand what you want.

Can you show us a picture of what you want?

ok, now I have empty, good, Full and I need add one more is (very good).

than I need add text when be( just) Full show me text like (T1 location in building 1) .
